Using additional heating provided by neutral-beam injection, the START spherical tokamak at UKAEA Fusion Culham has achieved high- (ratio of volume average plasma pressure to vacuum magnetic-field pressure) values of , more than twice the value previously obtained in a tokamak. These plasmas reach normalized beta values of at values of auxiliary heating power comparable to the ohmic power. Operation at high normalized current is observed, so that the plasma current exceeds the central rod toroidal-field current for the first time in a hot tokamak.

追加の加熱を中性粒子ビーム入射によって行うことで、UKAEAフュージョン研究所のSTART球状トカマクにおいて、高ベータ値(体積平均プラズマ圧力と真空磁場圧力の比)が達成され、その値は従来トカマクで得られていた値の2倍以上となった。これらのプラズマは、オーム加熱と同等の追加加熱電力において、規格化ベータ値が高い値を達成している。また、高規格化電流での運転が観測され、プラズマ電流が中心導体のトロイダル磁場電流を初めて上回ることを、高温トカマクにおいて実証した。
